#include <string.h>

char *strnul(char *s);
const char *strnul(const char *s);

strnul() calculates the position of the terminating null byte ('\0') in the string pointed to by s.

It is equivalent to both of the following expressions:

s + strlen(s)
strchr(s, '\0')

strnul() returns a pointer to the terminating null byte in the string pointed to by s.

For an explanation of the terms used in this section, see attributes(7).
